Alternative transportation choices

Vehicles are responsible for approximately 20% of the annual greenhouse gas emissions in the United States.

Travel by train or bus instead of airplane when available.

Purchase a car with the highest gas mileage available.

Plug-in hybrid vehicles will likely be available in three to four years, allowing cars to exceed 100 miles per gallon. By using alternative energy for a home, plugging these cars in to the electrical socket at night for battery recharging can shift a car's fuel source from gasoline to home- or grid-supplied renewable energy.
